` s claims. (c1. zia-12s) This invention relates to a spool or reel ofthe type formed of sheet stock and is a continua-` tion in part o f mycopending application, Serial No. 190,894, filed February 17, 1938, nowPatent No. 2,258,580.

The invention has for one of its objects to provide a spool or reelwhich will have unusually strong heads so that when copper wire isreeled upon the spool and heated for annealing, whereby there isprovided considerable expansion because of the greater coeicient ofexpansion of the copper than the gsteel of the spool, the strainsexerted will be resisted and the heads will maintain their shape inplanes at right angles to the axis of the barrel.

of wire into crevices I have so arranged that even though there openedup. AndI Another object of\the invention'is the provision of a structurewhich will so. support the stresses as to remain mit of high speeddrawing without wobbling or chattering of the spool on its supports.

Another object of the invention. is to prevent the entry of wire intothe seam between the barrel and the. flange of the head which contactsthe end of the barrel.

Another object of the'invention is to so relate the head and the barrelthat, even though there be accomplished.

With reierence,to the drawings, I0 designates concentric whereby to per--the barrel be movement of the head relative to the Abarrel in adirection axially of the barrel, still no seam will be opened up intowhich wire may enter.

With these and other objects in view, the invention consists of certainnovel features of confully described, and

struction, as will be more the appended claims.

particularly pointed out in In the accompanying drawings: v Fig. 1 is asectional view of a spool embodying this invention;

illustrating a diner-- Fig. 6 is a sectional view ent manner of weldingcertain of the parts in position. i, vIt is round in the use 'or spoolssuch as are used in .annealing copper wire that when the loaded spoolis`heated the expansion of the lcopper wire than the expansion o1 the steelof the spool causes tremendous stresses to be exerted on the heads oi.'the ing or the heads o! the spool or of the head axially along thebarrel. Such axial movement in some cases may cause lan opening spooland often a warp-Y some movement of the joint so that wire on the spoolmay enter the same; and in order that the wire may be. drawn at highspeeds it is essential that the spool be accurate and concentric withthe center hole that' the strains may spool from becoming eccentric-orany parts from i moving beyond the tolerance allowed for high speedproductionpand the following is a more detailed description of .the ofthis invention, illustratingv the preferred means by which theseadvantageous results may or the spool and Il the heads of the spoolwhich are formed from sheet stock as -shown more fully in Fig. 2. Thereis a center hole l2 in the head Il of a'size substantially the size ofthe outer diameter of ther barrel I0 so that the barrel I0 will extendinto the hole l2 and through the head substantially the thickso that theend I2 of the barrel will lie substantially ush with the outer surfaceIl of the head I l.

The head and barrel are secured inthis relative vposition by areinforcing plate sleeve It extending inwardly therefrom and of a ,ly ofthe end 22 of the curved surface 3l o! diameter to closely nt the innersurface l1 of the' barrel, while the plate I5 engages the outer surfaceIl of the head Il. Thus, there is formed about the juncture or seam thebarrel l0 an L-shaped whichwhen serves to maintain these two tion.

The sleeve' I. may terminate as shown in Fig. '4, or it may extendradially inwardly as at Il to the center tube reinforcing member at 2lalong the .center tube to be engaged at its end by the rollingoutwardlyand backwardcenter tube as illustrated sleeve may extendradially inshown in Figs. 1 and 2,' thence in Fig. 5; or thev wardly asat 24, as axially outwardly as at O wardly as at 26 and then turninginwardly, again axially as at 2l to engage theabutment 28 raised atintervals from the stock ofthe tube I9 for such abutting relation, whilethe thinned edge of this tube I9 may be rolled outwardly, about the thevrtions 2!k as atl to lock this reinforcing member centrally in presentembodiment i of the head Il and to the head and the barrel in thisrelative posi,-v

25, againl radially inposition. The outer surface 32 of this portion 23is in substantially the same plane as a tangent 33 to the rolled edge 34at the periphery of the head so that the spool may be set upright uponits end and may rest upon the surface 3 2 and edge 33 for bettersupporting of these spools in this position, such, for instance, asstacking a sexies of spools one on top of the other endwise.

In order to secure the reinforcing member to the barrel and head, I willweld the same to .the barrel through the sleeve portion IB as indicatedat 35 and then the reinforcing member able weld as at 36.

The weld 35 may take the form of a continuous resistance weldas shown inFigs. 1, 4, and 5, or the' form of a series of spot welds as shown inFig. 6 as at 31; while the weld at 36 securing the plate Il to the headIl may be in the form of a continuous resistance weld or preferably inthe form of spot welds in staggered relation about two diiferent'radiifrom the center axis as illustrated in Fig. 3.

The foregoing description is directed solely towards thevconstructionillustrated, but I desire it to be understood that I vreserve theprivilege will weld the plate I of to the head by a suitof resorting toall the mechanical changes to which the device I claim:

1. In a reel or spool of sheet metal a head having a central openingtherein oi' approximately the size of the outer diameter of the barreland with the surface defining said opening relatively smooth andunbroken, a barrel extending into saidopening, a central tube, an endplate abutting the outer surface of saidvhead and having a ilangeextending into the opening is susceptible.

e ing relatively in said barrel along said barrel and then extendingradially inwardly, then outwardly axially of the barrel, 'thenradially'inwardly to engage said tube, and a weld located between saidflange and barrel to hold said head and barrel in aslsembled relation.

2. In a reel or spool of sheet'metal a head having a central openingtherein of approximately the size of the outer diameter of the barreland with the surface defining said opensmooth and unbroken, a barrelextending into said opening, a centralvtube, an end plate abutting theouter surface of said head and having a flange extending into theopening in said barrel along said barrel and then extending radiallyinwardly, then outwardly axially of the barrel, then radially inwardlyto engage said tube, a weld located between said ilange and barrel, anda weld located between said plate and head to hold said head and barrelin assembled relation.

3. In a reel or spool of t metal having a head at each end thereof, eachhead having a central opening therein approximately the size of theouter diameter of the barrel and with the edge of the opening smooth andunbroken, a barrel having continuoussurfaces at the end portions thereofextending into said openings, and plates abutting the outer surfaces ofsaid .heads and each plate having a continuous unbroken circular flangeextending into the opening of the barrel, the free ends of said flangesbeing spaced from each other and a weld located between each oi saidflanges and the barrel and about the periphery of the barrel to holdsaid heads and barrel in assembled relation.
